the order of evalution will be left to right -- the first case is vm ==
null; if this qualifies the if statement will branch into executing code;
otherwise vm.getType() code will be executed (i.e. vm is not null); now here I
think you're suggesting that perhaps vm.getType() may return null in which case
we may have a NPE (unlikely based on db contraints (the type column should not
be null), but I'll modify as suggested.
